Hand sanitizer and some listerine can help at least a little bit with getting rid of jock itch so it's good to apply some listerine and hand sanitizer to the jock itch.
But a better home remedy for curing and getting rid of jock itch that I find works better than the Liserine or Hand Sanitizer is Apple Cider Vinegar.
Mix two tablespoons of apple cider vinegar in two cups of warm water and then wash the Jock Itch infected area with this solution and allow it to dry on its own.
I had to apply the Apple Cider Vinegar and water mixture to the Jock Itch for 4 days until the Jock Itch fully went away but it did work and worked better than the hand sanitizer and listerine.
